Not that familiar with the surge brakes on this trailer. Brakes seems to work well, but the left braking wheel gets hot and smells like hot brakes after about a 30 minute haul. Obviously the pad is creating friction. Is is normal/abnormal? I can understand a little warmth but this seems more than normal. The other side is totally cool. What is a good way to test the braking system? Thanks... |

It sound like the caliper is frozen. Not returning to rest. |

Sounds like you have a sticking wheel cylinder. You may have to disassemble the side that is getting hot and push the brake shoes side to side and watch the plungers move side to side. Or your surge cylinder on the tongue is starting to stick and not releasing the pressure which is holding the brake against the drum. My old trailer with surge brakes used to stick and cause a vibration after braking so I would have to accelerate with a jolt to release it. I now have electric brakes and will never go back to surge I have more control in stopping. I trailer every where I go up and down 6-7% grades at times so for me it works a lot better. It may also be time to have your bearings packed which could also be causing your heat issue. |

Stuck caliper piston. Time to pull the caliper off and check for corrosion. Not too hard a job once the trailer is jacked up. If the piston is very corroded, you might be better off buying a rebuilt caliper. Good time to bleed the brakes anyway, so 2 birds with 1 stone. After you clean up the piston (or before installing a rebuilt caliper), try to get some caliper grease under the rubber boot, between the boot and the piston, to keep water out (don't tear the boot!). The best way to do that is to force the piston partially out of the caliper, smear grease over the outside of it, then use a huge C-clamp (old skool) or a caliper compression tool (new skool) to push the piston back in. |

Disc brakes can be prone to sticking caliper pistons as drum brakes are prone to sticking wheel cylinders. In the case of drum cylinders I pack the boot with OMC triple guard grease and seal te boot to the cylinder with high temp RTV. If I had discs I'd seal up the space around the caliper seal with the same grease. They stick because of deposits left when water evaporates. |

Is it just me or does his boat seem to be nose heavy. the front tire looks like it is bearing the majority of the load. so if there was too much tounge weight couldnt it apply brakes slightly |
